This paper focuses on the process of Computer Aided Design (CAD) diffusion into a group engaged in the development of innovative products. Adopting an ethnographic approach, we build a grounded theory for interpreting CAD usage in terms of the interplay between variables such as management orientation, training, actors' specialisation and deskilling, availability of shared archives, technological discontinuities between organisational areas.  相似文献

ABSTRACT In this paper we provide a proof of the ‘Granger representation theorem’ starting from Phillips' triangular representation of a cointegrated system. Proofs of the theorem have already been provided but starting either from the MA representation or from the AR representation. Conversely, we derive and characterize analytically the MA and the AR representations in terms of the parameters of the triangular system.  相似文献

The authors investigate the differences in margins of export and domestic markets for Spanish manufacturing firms in the period 1990 to 1997. They estimate jointly a multiproduct cost function, a variable factor share equation, and two price/marginal‐cost margin equations. The results indicate that the marginal cost of production sold in export markets is slightly greater than in domestic markets. At the same time, the price/marginal‐cost margins in export markets are smaller than in domestic markets. There is also strong evidence that margins are procyclical in domestic markets, but this evidence is less clear in foreign markets.  相似文献

The structural transformation and aggregate productivity in Portugal   总被引:1,自引:0,他引:1  
We document the substantial process of structural transformation—the reallocation of labor between agriculture, manufacturing, and services—and aggregate productivity growth undergone by Portugal between 1956 and 1995. We assess the quantitative role of sectoral labor productivity in accounting for these processes. We calibrate a model of the structural transformation to data for the United States and use the model to gain insight into the factors driving the structural transformation and aggregate productivity growth in Portugal. The model implies that Portugal features low and roughly constant relative productivity in agriculture and services (around 22%) and a modest but growing relative productivity in manufacturing (from 44 to 110%). We find that productivity growth in manufacturing accounts for most of the reduction of the aggregate productivity gap with the United States and that a further closing of this gap can only be accomplished via improvements in the relative productivity of services. This paper was written while the authors were affiliated with the Federal Reserve Bank of Richmond. We would like to thank the editor, two anonymous referees, and participants at the Third Conference on Portuguese Economic Development in the European Context organized by the Bank of Portugal for their comments. All errors are our own.  相似文献

We introduce a simple model of oligopolistic competition where firms first build capacity, and then, after observing the capacity decisions, choose a reservation price at which they are willing to supply their capacities. This model describes many markets more realistically than the model of Kreps and Scheinkman [Kreps, D., Scheinkman, J., 1983. Quantity precommitment and Bertrand competition yield Cournot outcomes. Bell J. Econ. 14, 326–337]. We show that in this new model every pure strategy equilibrium yields the Cournot outcome, and that the Cournot outcome can be sustained by a pure strategy subgame perfect equilibrium.  相似文献

This article contributes to the current literature on mergers and acquisitions (M&As) by identifying the existence of waves and the determinants of M&A activity in the economies of Argentina, Brazil, Chile, Colombia, Mexico, and Peru. From a sample of 2,391 M&A announcements reported by Thomson One on these countries, applying the methodology proposed by Harford (2005), evidence of M&A waves is found for the periods 1995–2002 and 2003–2010, as reported for other regions in various international studies. After controlling for economic and business environment variables, as well as for profitability and book-to-market variables at the industry level, we find evidence that supports neoclassical theory as a main explanation for M&A activity but not for the misvaluation effect.  相似文献

Abstract

We investigate the impact of audit firm tenure, partner tenure, audit fees, fees for non-audit services and total fees on audit quality, as measured by discretionary accruals. Our sample consists of Spanish non-financial public companies for the years between 2006 and 2013. Results indicate that audit quality increases with audit firm tenure but decreases with partner tenure. Moreover, the level of fees paid to the audit firm seems to have a negative impact on audit quality, which is mainly driven by fees for audit services. In this regard, we do not observe any significant relationship between fees for non-audit services and audit quality. Our results also show that the negative relationship between either long partner tenures or high fees and audit quality does not occur when the tenure with the audit firm is long. Therefore, long audit firm tenures do not only seem to involve higher audit quality ‘per se’, but also moderate the negative effects of partner tenure and audit fees on audit quality. The results of this study, which are robust to several sensitivity checks, may be relevant for the current debate on auditor rotation and the joint provision of audit and non-audit services.  相似文献

A large body of literature argues that the characteristics of exports matter for economic growth and development because some goods trigger positive externalities or are subject to increasing returns. Thus, for policy purposes, it is important to know whether a country’s export basket enjoys these productive opportunities. They have been associated with technological content of exports. However, measuring them is not easy. Previous methodologies to account for exports’ technological content used either R&;D data or trade data. The former is used to account for knowledge-intensive activities during the production phase and the latter to identify levels of ‘sophistication’ of exports based on exporting countries’ characteristics. Building on these contributions, this paper combines industry-based and product-based indicators to circumvent some of the shortcomings of the received literature, including the product-industry controversy (i.e. are the actual activities during the production process or the product characteristics what better accounts exports’ technological content?). We use data from Uruguay on direct and indirect R&;D spending from public and private sources and also trade data to build the sophistication index corrected by quality. We contrast our findings with existing methodologies to highlight our contribution.  相似文献

This paper tests the pro‐competitive effect of imports on product and labour markets for Spanish manufacturing firms in the period 1990–2005. In doing so, it takes into account the type of imported products: final versus intermediate. Markups are estimated following the procedure suggested by Roeger and including an efficient bargaining model. The observed heterogeneity among firms is parametised to consider additional product standardisation and market concentration. The results support the imports as market discipline hypothesis for importers of final goods, while firms that offshore intermediate inputs show similar markups to nonimporters. Additionally, the union bargaining power is smaller for importers and the more homogeneous is the type of goods elaborated by firms.  相似文献
